Civil engineer here. I don't know why you're getting downvoted. Some neighborhoods weren't designed with space for trees. The city cuts out a square of concrete to plant a tree. Wilkens Av for example. The tree won't be healthy because it's not enough space for the roots. Not enough water. Unhealthy trees drop more leaves and branches. Dogs go to the bathroom. It smells bad. Sometimes the city does things half assed. Then it's worse than nothing at all. I don't blame people for not wanting a tree in that circumstance.
